This report is my 3rd sighting of very low flying dusk or nighttime objects with extremely bright white/red or white/red/green softly pulsating orb-like lights observed over shamokin, pa. the first sighting (with a video) was reported as mufon case #109243. my second sighting (no video) was a very short nightime sighting around 1 week before this sighting, approx 7:30-8pm, of a very low flying object over or just beyond the 500 block of n shamokin st. i was at the corner of n shamokin st and independence st. i only spotted the object for around 5-10 seconds, flying east. it was silent and pulsating red/green/white, flying south east, just above buildings. it was so low, just over buildings, that i was unable to keep the object in site for very long or make a video. for this third sighting, i was walking near the train tracks near the municipal building on n franklin st. (located at around 512 franklin st), looking north east/east towards the large medical/police/fire building. low flying air traffic is very rare in shamokin, and this object resembled my other two sightings (a pulsating bright globe-light object), so i immediately took a video with my iphone. it was silent. as the object moved east it went into a bright glare from street lights and i tried to reposition myself while recording. my phone had a difficult time keeping the orb-like light in focus.
